C#添加WebService服务实现天气预报

用C#做一个类似于上图的天气查询：

首先引用webservice服务

<?xml version="1.0" encoding="utf-8" ?>
<configuration><configSections><sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" ><section name="WeatherService.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" /></sectionGroup></configSections><startup> <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.2" /></startup><applicationSettings><WeatherService.Properties.Settings><setting name="WeatherService_Weather_WeatherWebService" serializeAs="String"><value>http://www.webxml.com.cn/WebServices/WeatherWebService.asmx</value></setting></WeatherService.Properties.Settings></applicationSettings>
</configuration>

然后创建接口：


using System.ServiceModel;namespace WeatherService
{interface Interface{[OperationContract]//得到天气具体情况string[] GetWeatherbyCityName(string cityname);[OperationContract]//根据省份获取对应的城市string[] GetSupportCity(string proviceName);[OperationContract]//获取省份string[] GetSupportProvince();}
}

实现接口


namespace WeatherService
{class WeatherServer : Interface{public string[] GetSupportCity(string proviceName){//获取服务对象  调用网站提供的方法Weather.WeatherWebService service = new Weather.WeatherWebService();return service.getSupportCity(proviceName);}public string[] GetSupportProvince(){Weather.WeatherWebService service = new Weather.WeatherWebService();return service.getSupportProvince();}public string[]  GetWeatherbyCityName(string cityname){Weather.WeatherWebService service = new Weather.WeatherWebService();string[] s = new string[23];s = service.getWeatherbyCityName(cityname);return s;}}

创建界面

using System.Threading.Tasks;
using System.Windows;

}
